The idea is to have an option to upload the current project file with CHMOD 600 (readable & writable only by the owner) when uploading the files to the server.

Refering to some posts (ex :http://answers.websitex5.com/post/37676) it could be a good way to provide security and be able to recover the last project in case of computer problems.

So, we could be able to download the last project file from the server and continue to work.
